The contact owns a 2012 Ford Fusion. The contact stated while driving at approximately 40 mph, the brake pedal was depressed; however, the brakes failed to engage. The contact stated that the parking brake was used to slow and stop the vehicle. No warning light was illuminated. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the brake master cylinder needed to be replaced. The vehicle was repaired; however, the failure persisted. The manufacturer was notified of the failure. The failure mileage was 137,221.
Upon applying brake pressure, the pedal must travel a significant distance before any braking is felt. My car has had new brakes put on, where the mechanic has said there are numerous complaints from owners with the same car. Braking distance is significant and I am able to feel the floor with my foot. This should not be the case. Ford does not seem to have a solution, so they continually push it under the rug. I have verified that my master cylinder is working as expected with no air in my lines. I do a lot of freeway driving, but in order to stop on time, I have to get off the freeway doing 10 mph less to ensure I can brake in time.
The brakes are "spongy". Took it to our mechanic who replaced the master cylinder twice and the brakes were still "spongy". He looked at the brakes and they looked good. He recommended that the abs sensor be replaced, but Ford wouldn't sell it to him. So, we took it to the Ford dealer and they replaced the brakes, calipers, etc. And the brakes remain "spongy". They said they needed to replace the master cylinder, but it is brand new.
The brake pedal is soft and travels further than normal. Braking distance is significantly increased. I brought the car to the dealership and turned out that the hydraulic control and the electronic control units are both faulty, based on some research it appears this is a known issue. It has a new master cylinder and brakes have been bled professionally. This did not cure the problem. It is unsafe. I want the dealer to do something about this at no cost to me. This is a recall item for 2010 Fusion, but not 2012. Why??? I've seen several complaints about this same issue why hasn't anything been done,safety should be top priority.
On occasion when the brakes are pressed it simply falls to the floor and has to be immediately repressed. It has a new master cylinder and brakes have been bled professionally. This did not cure the problem. It is unsafe. I want the dealer to do something about this, no cost to me. Ocures while in motion.
Brakes began to feel spongy. I had a small accident when I could not brake causing damage to another's car. Replaced the brake pads, had the system bled but now I have no brakes. I have no brake pedal at all. Replaced the master cylinder, front calipe, brake booster, and brake still have no brake pressure at alll.
While driving down my street going about 10 mph. My break peddel went to the floor with the sound of loud grounding. I took the car back to tbe house. In the past week a break booster new front and back pads 1 caliper a master cylinder and abs module have been replaced. Breaks are still non existant.
On cold starts this summer I back out of my driveway and press the brakes to stop and the brake pedal is rock hard and I can't stop. This is going to be my third time for this problem. The dealership has replaced the brake booster, master cylinder, brake fluid reservoir and brake booster check valve and vacuum hose.
